Valency Valence Electrons • Concept of Valency • Atoms and Molecules • Periodic Table • Variation of Valency Across Period, • Variation of Valency Along the Group • CHARACTERISTICS OF PERIODS AND GROUPS • On moving from left to right in each short period, the valency of elements increases from 1 to 4 and then decreases to 0 (zero). • All the elements of a group of the periodic table have the same number of valence electrons. • Valency of group 1 elements is 1 • Valency of group 2 elements is 2 • Valency of group 13 elements is 3 • Valency of group 14 elements is 4 • Valency of group 15 elements is 3 • Valency of group 16 elements is 2 • Valency of group 17 elements is 1 • Valency of group 18 elements is 0 • #valency • #valenceelectron • #PeriodicTable • #Scienceclass10 • #ChemistryClass10
